Researchers develop frequency-selective surfaces
The growing number of devices connected to wireless networks has highlighted the need for innovative solutions to ensure seamless connections. Now, researchers from Nagoya Institute of Technology have introduced a metasurface that can distinguish wireless signals based on both frequency and pulse width. This metasurface can be integrated into antennas to accommodate more devices within…
Research shows improvements for fast-charging of Li-ion batteries
Researchers at Chung-Ang University used high-concentration electrolytes to improve safety and prevent cell swelling caused by lithium plating. To achieve a greater adaption of electric vehicles, the automotive industry needs fast-charging batteries that don’t compromise energy density. Lithium plating for ultra-fast charging raises safety concerns due to high cell polarization, requiring careful attention. During fast…
